Join Astro, the robotic superhero with a human mind, in a quest to reunite the robotic race with humans. Astro uses his seven super abilities to face off against the likes of Atlas, Blue Knight, and more than 40 other characters. The game brings classic 2D gaming to the Game Boy Advance along with an original seven-episode story. Playing as Astro Boy, you'll learn about justice, compassion, evil, courage, and the history of Astro Boy--all while building Astro's Omega Factor and strengthening his character and superhuman abilities.
Metro City is a disaster zone and it's Astro to the rescue! This young robot with human emotions is small but mighty with six incredible super powers. If he can muscle through the massive plasma-oozing power plant, he's in for more trouble with swarms of pesky hammer-swinging bats - and that's not all. It is up to Astro to bridge the gap between humans and robots, so, Astro must quickly develop his human traits or his "Omega Factor." There are over 50 Tezuka characters, including Atlas, Dr. O'Shay, Zoran, and Dr. Tenma, that help Astro understand tenderness, justice, evil, and above all, courage, as he journeys through the futuristic city, Cruciform Island, and other out of this world locations.
